    So I’m currently rebuilding a dt125r as nut and bolt restoration and considering/most probably will be putting a dt200r engine in to replace my current just want to know what are everyone’s experience with the dt200 engine, what’s Involved, what do I need, and anything related to doing this swap

    Will be posting my build soon when I have a good inventory of pictures to show you all and get you hooked into knowing what’s next 😉

    @mhbikesnbits Ohh how exciting!

    I look forward to seeing it.

    Depends on which DT200R Engine you're going to use, one is vastly superior to the other, 3XP00 I believe is the one you want.

    Ultimately, it's still no match for a YZ250 Engine etc, but it'll be a nice upgrade.

    Read @Louis-James build as he has that well documented.

    Engine should be straight swap, if you want to transplant the cylinder to the bottom end then you will need to do some modifications to the crank case.

      @Calum yz engine would be nice yes but there made for racing not for road use so would require a rebuild far to often for what i need looking to do a straight swap for the dt200 engine I may even use my old dt 125 engine afterwards to put in a yz 125

      Need to souce a engine too there’s one on eBay from Poland that I have had a look at but not sure

        DT200WR and DT200R both fit straight in.

        Both will need carb, pipe and exhaust in the case of 200WR.

        Neither 200 engine is bonkers like a YZ engine, however the 200 is like the 125 you always wanted and has more grunt.

        The 200WR engine is slightly more powerful than the 200R and has a nikasil liner rather than a plain steel one.

        I have a DT200WR and a TDR125 Belgarda and I'm probably going with a 200R lump in the Belgarda just because it will look right and need the least mods.

            @pedrobatista10 Stock 125cc is most likely faster than a stock 170 Athena. THEY ARE JUNK.

              @Irongamer727 you mean stock athena? because a modified athena its very good. one of the fastest dtr 125 in portugal use them heavily modified

                  @pedrobatista10 That's misleading as they swap from one rider to another. It's probably easier to say which_is_which, by naming the rider with or without gloves. These idiots never ceases to amaze me with all these vids of fast/stunt riding and NO FREAKING GLOVES!!!

                  Cool vid though, personally I'd go for the 200cc engine as you will get better reliability for-sure. 😉

                      All the BAR bikes are tuned

                      Also they always have super skinny wheels and low boy exhausts 😞

                        @Nottsbiker cheers for your feedback thinking the dt200r engine easier to source I think

                          also I take it the dt200 engine can be derestricted in a similar fashion to how the 125s are

                            @mhbikesnbits Yes to a certain extent, but I would not ride it on a CBT or with 'L' plates tho, as you'll just be asking for trouble. 😉

                              @mhbikesnbits not restricted in any way. Always tuneable 😉
